Welding Cast Iron Engine Blocks. The broken cast iron pieces were TIG welded using a 2 Thoriated Tungsten and Argon Gas. With really good results but if you still plan on welding that block make sure you get good quility rods and say lots of prayers.
Not saying that it cant be done but after seeing what problems that can come from trying everything and every method I finally went to the pinning tech. It is possible to weld cast iron using an arc welder and the proper welding rods but that often can cause deformation to your engine block or leave the welded area far more brittle and. The welding may cause the deformation of the engine block or make the weld area far more brittle and susceptible to cracking.

Start applying the nickel electrode at the bottom of the crack and work in an upward direction of the crack. MIG welder is highly possible for welding cast iron. Start applying the nickel electrode at the bottom of the crack and work in an upward direction of the crack. Step 1 Keep the cast iron out of the range of 150 to 500 degrees Fahrenheit 65 to 260 Celsius.
